Engine Timing Belt Change Interval
 
I am still working on a set of technical notes that relate to engine timing belts.

I have made a thorough check of the Owners Handbook, the Service Portfolio and the Brooklands edition of the Rover 75 and MG ZT Workshop Manual and have not found any written information about the intervals at which the engine timing belts should be changed.

Originally I was informed by my Rover dealership here in Melbourne, Australia that the timing belts should be changed at 145,000 kilometres or after six years use, whichever event came first. I have not yet seen this important information written in a MG Rover produced document. To me, this omission is extremely strange.

My selling dealer is now defunct, so I can't check there.

Does anyone in our group know where this important information was written for owners to act upon?

Having visited several Website forums on this subject, I have found out that Holden/Vauxhall Astra/Vectra intervals have been reduced significantly, as have those for Audi cars, in the interest of reducing warranty costs. Bung it back on the customer! Noted also, is the fact that the Rover KV6 and 25K4F engines enjoy the longest timing belt change interval of all.

I believe this subject is/was important enough to warrant a copy of pertinent written notification -- somewhere.

Thanks for help, again,

My 2003 service schedule from Rover, and the Haynes workshop manual, quote six years or 90,000mls. It's a good idea to reduce this a bit bacause of the disasterous results from a broken belt, so why risk it.

Hi Mike and welcome....

After reading a few threads here I've got the impression that most are changed around the 90,000 - 100,000km. mark. I think this is mainly due to the fact that on average most people (in UK) do about 16,000km a year, so 6 years. I'm sure you can do the math...... :D

Hope this helps.

And of course the R75 diesel has a chain drive which will last the life of the engine.

Here's the 2004 official MGR service listing. Cam belt replacement at the recommended 6 years/90K miles is the most cost effective schedule. The OEM belts have a notional ten year life, so MGR knew what they were doing in setting down the schedules. Of course, many people change stuff much earlier, which is their prerogative.

Hi Folks.

Thanks for that information, and T-Cut, thanks for showing the Service Schedule.

I am still surprised that there is no mention in either the Workshop Manual, nor the Owners Handbook. Especially when the Handbook is of such quality.

I have certainly taken on an interesting task!

Thanks again,

Mike A.

Dear T-Cut,

I have had a look at the Service Schedule. Most enlightening, as I have never seen one before! Even though my car was a new purchase.

May I use a portion of the schedule, that shows cam belt change interval, in my notes?

The notes are for club use here in Australia. They will probably be posted on the Internet.

Thanks,

Mike A.

It is strange from our point of view. I guess the Workshop Manual describes 'how to' rather than 'when to'.

MGR didn't anticipate that the owners of these cars would do their own servicing or understand anything remotely technical. That's why they fitted the silly temperature gauge that doesn't say anything but 'everything's fine'. If it goes into the red, the Handbook says 'stop and seek qualified assistance.' They (perhaps correctly) assumed that the driver wasn't likely to be 'qualified'. Indeed, I suspect the vast majority of owners never check the coolant level more than annually, never mind attempt servicing.

EDIT: Please use the servicing information as you wish. Many UK owners will have received a copy of this back in the days.
